Abstract: Disclosed herein are systems and methods for detecting an event while a powered system is powered off. An exemplary system comprises an event input that is configured to detect an electrical signal created by an event while the system is powered off; a zero-power event memory configured to receive the electrical signal from the event input and use the electrical signal to store an indication that the event occurred, wherein the zero-power event memory is configured to store the indication that the event occurred at least until the system next powers on; a read subsystem that is configured to, when the system powers on, access the zero-power event memory and determine whether or not an event occurred while the system was powered off; and a reset subsystem that is configured to, when the system powers off, cause the zero-power event memory to reset to a state indicating that no event has occurred.

Abstract: A method of installing a filter into an electronic circuit board is provided. The method includes inserting a second section of the filter into an aperture defined in the electronic circuit board, such that a first section of the filter is secure against an electronic circuit board first surface and a first lead of the filter extends to a solder pad on the electronic circuit board first surface. The method also includes coupling a second lead to a second contact of the filter such that the second lead extends to a solder pad on an electronic circuit board second surface. The method also includes reflowing the circuit board such that the first lead is soldered to the electronic circuit board first surface, and the second lead is soldered to the electronic circuit board second surface.
